Application filed Marctf, .1907. -Seri-a1-No.-362,7s55.

To rzZ "whom it may-concern Columbus, in the countyor Franklin, in the Staten/t Ohio. have invented a certain new.

and valuable Improvement in Cash Registers,zlndicators,=and Recorders. of which the following is a description, reference being had to the accompanying drawings, which forsna part of the'applioation.

The distinctive purposeof this invention is to modify some of the minor details of the Hallwood constructions, whereby the same may bemanufactured-and used absolutely free from infringement.

The first object ofmy invention is to provide-improved means whereby the operator compelled to depress a key of each class with which the machine may be provided before a transaction can be registered, screened; indicated or recorded. I

The second object of my. invention 'is to provide, in registers having a plurality, of series of keys, such as value,-initial and department keys, suitable interlocking mechanism between the keys of the different su'c'h mechanism requiring .the operation of both an initial and a department key, in conjunction with a -value key or keys representingthe amount of the transaction, before the machine can be operated. Such interlocking mechanism also controls a change or no sale key, the sa-me being preferably included in the series of department release keys and being normally undepressiblqsthe same being released or rendered depressible upon the operation of a-lerlds initial-key, unless such operationhas b on accompanied by the operation of a va ue key, in which event the no-sale key is rendered entirely undepressible for that operation of the machine. By the means of this interlocking mechanism, a correct and complete indication, registration and record is compelled at eac operation of the machine, the indicators and recorder showing not only the character of the transaction and the amount involved, but disclosing the identity of the clerk. responsible for the transaction.

The third object of my invention is to provide for a simple form of full stroke.

mechanism, adapted to prevent :the retraction of any release key after its partial depression, and to thereby require the full depression of apartially depressed release key so that the completion of each particular transaction is impeinti-vebefore the machine can .be again operated.

The fourth ob ect of my invention is to provide a screen or shutter adapted to conceal the target indications until the act of registration 1s complete, thereby compelling the clerks to promptness in returning the partially operated parts to normal position.

The fifth object of my invention is to eliminate the so called main yoke from the construction of the-said Hallwood cash register, which yoke has heretofore been used forinwarting movement in one direction to the elements 1n turning the counters and indicators.

.The sixth object of my invention is to elin inate the positive coupling devices between the indicator operating levers and their respective yokes, it having been assumed heretofore that such devices are desirable for preventing a possible overthrow of the indicator wheels.

The seventh object of my invention is to combine in one machine the hand lever mode of operation with the cash drawer mode of operation whereby the operator may leave .the cash drawer in its open position and perform the transactions on the machine by means of the hand lever or he mayperform such'transactions bythe means of the cash drawer, means being provided whereby the hand lever may be disconnected from themachine when the transactions are being performed by the cash drawer.

The eighth object of my invention is to provide means for preventing the too rapid operation of the machine and to thus make it impossible'to give the parts such an impetus as will cause them to be carried too far or overthrown-due to their momentum.

The ninth object of my invention is to provide improved means for controlling the detents for the keys, the detents being supported upon movable means that areso displaced upon the initial movement of a release key as to effectually lock all k ys in the positions they maythen occupy.

The tenth object of my invention is to provide improved means for controlling the adding pawls. whereby said pawls are-effectually loc ti-Cl to their respective adding wheels at all times except during the time intervening between the depression of a reof the operating parts toward their return or normal positions.

The above and other objects of the in vention will bemore fully set forth in the following specification, which is descriptive of the accompanying drawings, in which- Figure 1 is a. front elevation of a cash register, indicator and recorder containing my improvements. Fig. 2 is a. vertical, transverse section on a plane at the right of the department bank of keys, showing drawer release and resetting mechanism, and also the means for positively removing the reciprocating lock bolts into and out of en gagement with the adding wheels, Q

General description-In the following description of the construction and oper ation of the various parts of the machine,

the same characters indicate identical oarts throu hout.

1 denotes the outside frames and 1- the center frame, all of which are firmly secured to the upper base plate 1 2 is the main shaft fixed in its hearings in the leftside frame 1 and the center frame 1. Upon this shaft the stepped sectors 3 are loosely mounted, 2 is an oscillatory extension of shaft '2, having its hearings in the right side frame 1. and in the recessed end of'shaft 2, which is bored out for that purpose; t is shaft fixed in the frames 1 and 1 to carry the indicators 5; 6 is a shaft journaled in frames 1 and 1 to carry the'sector gears 7 that operate the indicators 5; 8 is a dash or blind for concealing the indicator wheels during the operation of the machine 9 natcs the value keys, 10 the clerks irkeys and 11 the department release keys; 12 represents the adding wheels; 1%, the bandle by which the adding wheels 12 are turned to zero; 13 is the cash drawer; t is the printing device; 15 is the type carrying sectors; 16 is the sector which operates the ink ng and tape feeding devices of the .lease key and the beginning of movement 1 {g oser/o printer through the pinion 16"; 17 represents the yokes which are 'set in position by the rotation of the stepped sectors 3 and control the position of the type carrying sectors 15, the adding wheels 12 and the indicattn's a.

To enable the atleinlant to return the par- 253,740 and 551,411 except that the manually operated extension .8 in this application is i-en'iovable and may be entirely removed and dispensed with when an exclusively drawer operated machine is desired.

Drawer mode of operation-To adapt the machine for operation by the drawer, the main operationg lever 18 is provided with a foot 18, saio. foot being at the lower end of the extension 18 of said lever and being engaged by aroller 19 that is journaled in the rear end of the c sh drawer 13. \Vhen the operating parts of the machine are in normal position, he yokes 17 are supported by the rear arm of the lever 18, which is held against movement by a latch plate 20. This latch plate, which is pivoted on a rod 21, is provided with a hook 20. that is adapted to engage a stud 22 on the forward arm of the operating lever 18, being pressed against the same by a spring 20 hen thekeys have been operated in the usual mannor, the hook 20 is disengaged from the stud 22 and the cash drawer is released, as will be lnzreinafter more fully described. This leaves the lever 18 free to oscillate the shaft 2 and permits the spring operated yokes 17 to assume positions corresponding to the values and to the positions in the keyboard of the keys that have been depressed. lVhen the drawer is released, it is thrust forward by the spring 23 in the usual manner, the drawer being by the foot 18 of the'lever 18. l Vhen the drawer is closed, the roller 19, hearing against the foot 18, lifts the lever 18 and the yokes 17, and moves the stepped. sectors 3 and type sectors 15 to their normal positions.

Combined injmtl Ze'rvr (will (ZIWIIHYJ mode of operation-When, however, it is desired to operate the register with the drawer open. the hand lever 18 is connected tothe for-- ward end of the lever 18. This hand lever is hooked around the shaft 2 and is normally held in its most elevated position by.

a spring 2 that extends from it to the rod 25. To return t'. initially operated parts, this hand-lever is drawn down, where-' tcr to its normal and locked position. As the hand lever 18* approaches the end of itsdo-wnvvard travel, a stud 18 thereon con tacts with a finger 20 on the lock plate 20 and forces the lock plate hook 20 into engagement with the pin 22, making thereby a positively operating lock. \Vhen the handlever is released it is-returned to its upper j to each frame 34 -s a 'detent plate whose outer edge-1s concentric to and immediately scribed, the machine may be operated either 'To release the (drawer. When the drawer 13 is pushed in,- it is engaged and locked by l latch plate is thrust rearwardlv by the dethe lock pawl 27,- which engages the catch 29,

the drawer being released in the following 3 manner: Pro ecting laterally from the lock i pawl 27 is a lug 27 which is engaged by an arm of the lever 30 that, is pivoted on the hook 32 on the detent latch 32 of the bank 1 of department or release keys. Said detent latch plate 32 is pivoted on the shaft and t caused to oscillate rearwardly when a department release key is depressed a cross pin 11 of any of the release keys 11 engag ing the detent latch plate of the department bank. plate 32 oscillates the lever it) so that the. rear end thereof. engaging the lug '27 lifts the pawl 2? out-- of engagement with the catch 29 when the drawer is free to be thrust forward by the spring 23. Th department release keys 11 are locked against depression. however, until a key in the value bank and a key in the initial bank are depressed; and the no-salc key 11* is undepressibl'e'until a olcrks initial key 10 has been depressed. 'lhe no-sale key is also looked against depression when a value key 9 is depressed. as will hereinafter appear. The constructimi and operation of the several banks of keys are as follows:

Value Zm7 's.-Tl1e key frames 34 of the value bank are supported on rods 2] and and they contain the keys 9,,the same being inside the line of cross pins 9. Each of these plates is guided in a slight rotary movement about the shaft 2 by pins 3% in the frame 34 which enter concentric slots 36 in the detent plates. Each plate is also provided with a series of hooks or detents 36, there being one of such hooks for each cross pin 9. The forward ends of these hooks are blunt, or are formed with faces that BXLCtlCl at substantial right angles to the lines of movement of their respective kcys.

Lying adjacent to each of the detent plates 36 is a latch plate 38, which also has its forward ed e concentric to and in position to be engaged by the cross pins 9. Said latch plate 38 has a slight rotary movement on the rod 33, being held in contact with the cross i pins 9 by a spring 38 that connects thenpper end. of the latch plate 38m a rod Pivoted on a rod 31 is a series of levers l0, there being one lever for each vertical row of value keys. Eachof said levers has a face l t) at its outer end that is adapted to be engaged by a snid 38 on the corresponding. latch plate 38-, whereby the lever 4-0 is caused to rotate on the shaft 31 when the pression of a key l). The said lever is bent laterally beyond the shaft 31, and thence forwardly. thus forming a second series of levers 40 each of which 'has a hook 450 that is adapted to engage with a stud 3 projecting laterally from the corresponding stepped sector 3, thus holding said sector against rotation when the yoke 17 of that bank is left unsupported during the movement of'the main operating lever 18. T The depression of a value key in any row of The oscillation of the dctcnt .latch the key hank releases the corresponding sector by lifting the book 40 from the stud 3.

Each of the detent plates 36 is provided near its lower end with a slot 36, in which operates a pin 37 on an arm 37, said arms being; connected to a rock-shaft 50. There is one of these arms for each of the dctents and the latter are usually held by these pins in the position shown. in Fig. 3, so that the cross pins 9 of the keys maypassl'ielow-the hooks 5-36 and be caught thereby in a. releasable position. When, however, the shaft is rocked to lower the detent plates, as here, innftcr described. the b unt faces of the hooks 3G'will he brought into position for intercepting the undepressed pins in the other keys of the bank, whereby all such undepresscd kcys-are securely locked against. operation;

filer/ls initial lcy/sz lhc clerks initial kcy bank is similanto that of the value keys,

37 of the value key banks, upon which latter studs and arms the detentplates of the value keys are supported.

Department release kc z s.The department bank also consists of a key frame 44, detent plate 45 and a detent latch plate 32.

t The keys ll are rendered normally undepressible by having their cross pins 11 normally'contact with the flat periphery of the detent plate 45. This detent plate is also guided in a slight rotary movement about the shaft 2 by the pins 44 which enter the slots 45 the plate being supported by a stud 47 that projects laterally from the free end of an arm 47 that is journaled on the rod 31. Said arm 47 is connected by a cross bar 48 (see Figs. 2, 5, and 6) to an arm 47 that. is also journaled on the rod 31 at the leftside of the value key bank, said cross bar and arms comprising a yoke. This bar 48 rests on the levers 40 so that when either of the said levers 40 is raised by the oscillation of the corresponding latch plate 38 of a value key bank the bar 48 and the arm 47 will also be oscillated suiiiciently to bring the beveled faces 45 of the hooks on the detent 45 into the. line of movement of the cross pins 11*}. Mounted rigidly on a shaft 50, which is journale'd in the left end frame -l and the center frame 1, are the rocker arms 37 and 43, hereinbefore' referred to. This shaft has, in addition, another arm 51 that is also rigidly attached to it. The arms 37 and 43 have the pins 37- and 43, respectively, whiclrare engaged in the slots 36 and 41 in the detent plates 36 of the value bank and 41 of the clerks initial bank, as before. described; but the arm 51 is connected to the latch plate 32 of the department bank by a link 52 so that, as the latch plate 32 of the department bank rotates rearwardly, the arms and 43 will also be caused to rotate slightly in a downward direction. This movement, however, must be preceded by the operation of the value and initial keys, so that the operation of the entire key board is as follows: When a value key 9 is depressed, the slot 36 permits the detent plate 36 corresponding to said key to be raised sufficiently to permit the cross pin 9 on the key to pass thepoint of its respective hook 36. The plate then drops by gravity until it rests again on the pin 37 In this position any other key in the same bank may be depressed, which operation will rock arm 43.

rcsultin releasing the key already depressed. The bar 48 is also raised, as before described. v When an initial key 10 is depressed, its cross pin 10 presses the shoulder 42 from under the stud 41, and the initial detcnt plate 41 is thus allowed to drop until the top of the slot 41 rests on the stud 43 on the The remaining keys 10 are now rendered inoperative, as their cross pins 1O are then in front of the flat faces 41 of the detent plate. The dctent plate 45 hav ing been raised by the oscillation of the arm 4-7, as before described, a key 11 may now be depressed. In so doing the cross pin 11, pressing againstthe detent latch plate 32 causes it to rotate rearwardly which rotates the shaft through the link and arm 51. The said rotation of the shaft 50 also carries with it the arms 3. and 43, whereby the detent plates 36 and 41 of the value and initial banks are dropped so that the lat faces 36 of the detent plate 36 is brought before the cross pins 9, thus rendering the remaining value keys inoperative. The dc tent plate 41 is now supported by the stud 41 resting on the lower end of the slot 42 and the stud 43 has moved toward the-upper end of the slot 41 Operating lever reZcase lrojecting from the side of the department latch plate 32 is a stud 32 for engaging with the front edge of the operating lever latch plate 20; and, as the latch plate 32 is pressed rearwardly by a cross pin 11, the stud 32 presses the latch plate 20 rearwardly so that the stud 22 on the operating lever 18 is released from the hook 20, thus permitting the lever 18 to oscillate the shaft 2 The rearward oscilla tion of the detent latch plate 32 also causes the hook 32 thereon to bear down upon the end of the lever 30 and thus raise the latch pawl 27 and release the drawer.

FuZZstm/ve deed/1e for release 7ee3 s.--l\ l1ei1 the department d etent latch plate 32 is forced re'arwardly, a stud 32, projecting laterally therefrom and having its lower face in the form of a knife edge, travels along the upper notched edge of a lug 53 which projects from the side of 'a lever 53. This lever is pivoted at 54 on the center frame 1 and is yieldingly supported in a horizontal position by a spring 53 so that, when a key 11 is partly depressed, the knife edge of the stud 32 engages with the notches on the lug 53 and prevents the return of the detent latch plate 32 to its normal position until it completes a full stroke, when the lug risesand permits the stud to pass below the same as the detent latch plate 32 returns to its normal position.

To prevent manipulation of department keysJ WVhen the detent latch plate 32 is forced rearwardly by a cross pin 11, the projections 32 on the forward edge of the said latch plate are elevated so as to extend aiid the latter againstreturn untilthe stud passes the lug '53". i

{the pendent arm 18 irom the main 0 1- erating'lever lB-is provide'd'Wi-th-a, slot 18, which embraces a-pin 555in a bl'ock 55 that is adepted'to slide forward on two parallel rods 56-, said rods being supported in up-' right flanges or posts 56 on'the top plate 1. The said-block 55 has a roller 55 journaled on one side thereof which roller is adapted to I move forwardly beneath a by a'sspa-Wl '57 that is-pivoted on the-rear en of the resetting lever 57 and rearwardly onthe-t'op-of the said pawl, so as to depress the said lever.

The lever 57 is pivoted on the screw 28. To

lift the detent plates forreleasing the de pressed keys, the lever 57 is also provided with a nose or shoulder 57' that projects under a bar 58 so as to be. in position for lifting the same. The said bar 58 is connect'ed at each end to arms 58 that are iournaled on-the shaft 33, audit is adapted to engage'the lowerends of the detent plates 3G, 41, and 45. Thus it, will bes'een that, as

the main operating lever 18 is returned to normal position, either by drawing down the hand lever 18 or by closing'the drawer 13, the sliding block 55 is moved rcarwardly,

the lever 57 is oscillated, as hereinbofore described, and the detent platesBG, 4:1 and 45 are raised high enough to allow thepross pins 9 10'"- and 11.- to escape from their several detents by which they were engaged; then, when the roller 55. passes oil' the pawl 57 andallows the .lever hi'to oscillate in the opposite direction, the detent-plat'es'tlmt have been raised by the'bar58drop to their normal positions. The latch plates 38, 42

and 32 are returned by the-springs 38 to their normal position against the cross pins of the several btinks 'of'keys.

4V0 saZc .7ireg .The above description of the constructionand operation of the departmentkey bank only included keys IL-or those having to do with general merchandise transactions, such ascash sales, money received on account goods charged and money :paid out all of which require the use of a vvalue key 9 as well as an initial key 10 (without predetermining se-.'

quence of operation) to renderthein operative. The remaining keyll ,r.-cal led the no sale or change key,'however, is normally depressible so far as the value keys 9 are concerned, as its cross pin 11 is in line with the inclined face of its corrcspondmg hook 45; but, when the detent 1 plate if; is raised by depressing a value-key 9, the flat edge 45 of-thc detent plate l5 is brought oppositethe said cross pin 11 and the no-sale keyis thereby rendered undepressible.- It is necessary, however, that of the slot 4 the initial detent plate, the shaft 50 could an'initisl key '10 be depressed before the key 11 canbe operated, for the following-reasons: The depression 'of the -nosale key causes the-oscillation of the department hitch plate'32, This, in turn, must cause the shaft 50 to rock. If, therefore, this shaft be held, or-if it be prevented from moving a distance 'suiiicient to permit the cross pin 11 of the no-sale'key to pass its corresponding hook on the detent plate 45,-the key will be locked out of operation.

By reference to Fig. l, it will be seen that the pin 43 is normally near the middle of the slot 41 When, however, an initial key 10 is depressed and the in 41 drops into the recess 42*, the initia detent plate falls-until the pin e3 rests inthe upper end Prior to this movement ofnot rock for enough to permit the nosale key to be depressed; but, lifter such move ment, the pin 4-3 has the full length of the slot il for iis movement, which permits-the shaft to rock fully and thus provides for the freemovement of the department deteut plate, so that the no-sale key can be de pressed. This feature ofthe interlocking mechanism between the clerks and the release keys is also operative when any of the release keys 11 is depressed. That is to before any rcleesekey 11 or ii" can be I pressed a distance sufiicient to release either the main operating lever 18 or cash drawer, its depression must have been precedet by the-operation of a clerhs initial key A l lndicaz mz-Each of the revolving targets or indicators 5, which are mounted on the shaft has a pinion 5 rigidly secured to, which pinion meshes with a geared sector 7 that mounted on the shaft Each sector 7 has areerwardly extending arm "7, which is connected-a link 60 that is loosely attached to a stud onrthe rear arm t. of

the corresponding stepped sector 3, so that,

when the opeinting mechanism hesbeen leased by the operation of the vsrieus .li ys, the oscillation of the sectors 3 to theposi tions that ere'controlled by the depressed keys, carries around the indicators into position fer exhibiting an indication that corresponds with the keys depressed. The slot or loop 60 in each of the links 60 allows the return of the stepped sector "Ste its not-- mal 'po, tion indepcn "n the spring (30 connecti the sectors 3 L. 7,, being put in tension the stepped se is returned tonorznal pnsitionby the ing of the drawer or by the operation e hand le er 18. The indicators are retain in then mounted on shaft (32 and which enga 'e with star wheels 5 that are rigidly sect l to the r spective indicators 5. The tension of the spring 36 suliicient to always main fly of the indicator,

set. positions 5y pawls 61 which are bators, where they will remain until the main tain the stud 3" in the lower end of the loop (30 unless the indicators are locked by their pawls 61. By using a spring of sutlicient strength for this purpose, no overthrow of the indicators is possible, and the use of complicated machanism for locking and unlocking the indicator operating devices and the stepped sectors is rendered entirely unnecessary. The indicators are released by the oscillation of the shaft 62, which tected by the lever 63, said lever being socured to the shatt'U-"i and being swung rearwardly when the stud 63 thereon is tree by the oscillation of the main 0, crating lever 18.

AS FI'@( /.'It has been found desirable to screen the indicators from view during their movements so that the operator cannot arrest the indicators and cause them to show any other registration than thatactually made by'the keys dcpr" "d, such false indications causing the cnmomer to be deceived. For this purpose ll provide two shutters 8, one to screen those indicators that are-read from the front and the other to screen the indicators that are read from the roar. Each shutter is carried by arms 8 that are journaled on the shaft-4. The arms .8 at the inner ends of the shutte have each a stud 8 projecting laterall nnrc'trom which studs rest on the shoulders 64 plate 6% (see 2). The said. plat is bifurcated at its upper end to embrace th shaft 4, and is slotted near its lower cut, through which slot passes a pin 65, the rod 1 and pin 35 acting as guides for the plate. The lower end of the plate 64 is partly beveled on one side, and is adapted to normalh rest on a stud 18 that projects laterally from the upper arm of the main operating lever 18, so that, as the lever 18 oscillates rearwardly, the plate Get and the shutters 8 will drop by gravity to conceal the indioperating lever 18 is again brought to its normal position, when the stud 18, hearing against the beveled face, of the plate 64-, raises it and the shutters to their normal positions. From an inspection of Fig. 2, it will be seen that the devices tor releasing the operated keys and for lifting the indicator screens are so timed in their operation that the keys are released before the indications are disclosed.

Register mcciuma's'lm lloosely journaled on the shaft 2 to the right of the operating lever 18 is a series of addin wheels 12' that are provided with peripheral ratchet teeth 12*. Adjacent to each wheel 1 is an operat ing lever 66 that is also 'journalcd on the shaft 2 said lever being extended rearwardly beyond the periphery of the wheels 12. Each of the arms (36 is supported on a separate operating yoke 17 by a. depending leg 66 A reciprocating locking bolt 66 is c m, .F 1,300,170

n'iounted on each arm 66 and is adapted to slide into and out of engagement with the teeth 12 on its respective adding wheel. Mounted on a shaft (37 by means of slotted arms (38, is a bar 68, said bar carrying a web or flange 68' which extends inwardly from each end of the bar 68, said web hav ing holes 68 to receive pins (57 which project from the shaft 67. From the lower cdgeof the bar 68 depend vertically disposed, parallel bars 68, said bars having their lower ends connect'edbya plate 68. hese bars are curved so as to be concentric with the shaft 2% There a bar 68 for each locking bolt (36 said bars passing through rccesses in one side of their respective locking bolts. Extending from each end or the plate 38 is an car 68 each ear having therein a hole through which extends a pin 69 that 'n'oj-ects from the rock shaft 69. Secured to the rock shafts 57 and 69 are arms 70 and 71, espectively, said arms being connected by a j The arm 70 is also connected to the 63 by a link 73. he construction such that, when the lever 63 is released and is swung rearwardly by the spring 63, it conn'nunicates' movement, through the links '78 and 79, to the arms Z0 and 71 and to the shafts (37 and (39, so that a parallel movementis transmitted to the bars whereby the bolts 66" are withdrawn from the teeth 12. The arms 66, being thus released from the adding wheels, may descend with their corresponding yokes When the ain operating l ver is again brought to normal position, the lever (33 is swung forwardly, drawing with it the links 73 and 72 and oscillating the arms 70 and J1 and the shafts 67 and 69, thereby forcing the bolts 66* into locked engagement with the teeth 12* before which they had stopped in their descent; and, as the yokes 17 are raised, there is effected an advance of the adding wheels 12, corresponding in degree with the values of the keys depressed. The bolts 66 being thus positively held in engagement with the teeth oi the adding wheels which theyentered, and being releasable only in the next succeeding opera tion of the machine, it is evident that it is impossible to cause an overthrow of the counting wheels by a violent operation oi. the machine.

FuZZ stroke device for the main operating; Zeoe-r.-l n nearly all forms of cash register construction, it is necessary, after a registration is commenced, that some device be provided to compel a. complete performance of the started registration before a second operation of the machine can be eiiected. For

secured to the block 55.

' normal positions by the springs 17.

It is obvious that in registering a sale by the keys of lower values, the travel of the yokes 17 is very limited, and that the operating springs 17" transmit little stress or jar upon the transfer'or indicating mechanism; but, when the keys of higher values are operated, the movement of the parts ferred to is accelerated and considerable inomentum is required. In a return of the main operating lever 18 to normal position by the extension hand lever 18 an ordinary -manua'l movement imparts little or no stress or jar; but, at times competitive salesmen strike a severe blow uponthe lever whenit is part way down, with a view to overthrowing the adding wheels and transfer mechanism, and thereby causing the addition of a larger amount than called for by the keys depressed. To overcome these tricks I use the governor shown in Figs. 1, 6 and 10, which comprises a shaft that is jonrnaled in a bracket 7 6, which is rigidly Secured to said shalt is a pinion 7 5 the same being so nositioned as to mesh with a toothed rack 7 4; that is secured to the side of the full stroke rack 74. The weighted governor arms 7 7 are journaled at one end on a pin 7 7 that passes-transversely through the shaft 75, which construction permits the arms to swing outwardly, due to centrifugal force, when the shaft 75 is rotated. The iournaled end of each of the arms 77 is formed with a shoulder 77*: Wh1ch bears against a disk 78 when the arms 77 are thrown outwardly, and presses said disk against a similar disk 78 that is rigidly secured to the hub 76 on the bracket 76. The disk 78 is free to move axially on the shaft 7 5, but revolves there: with, so that when it"contacts with the disk 78 the friction resulting therefrom retards the velocity of the shaft 7 5 and prevents e.\-

' cessive speed of the sliding block A sudden downward blow imparted to the partly depressed hand lever 18 will cause the arms 77 to spread outwardly and create suilicient friction between the disks 78 and 78 to an sorb the impact of the blow and pre "eat the transmission of its effect to the adding mechanism.

From the foregoing description it will seen. that the interlocking mechanism tween the keys of the key board 001'! depression of both a value and an initial key-before a releasekey can be operated to elfect-a transaction IHVOlVlILQ, a sale,.and

- that an initial key must be depressed in advance of the depression of the no-sale key.

This feature of the invention is of specialvalue in combination with the printing mechanism, as it insures a record showing what clerk is tobe charged with the responsibility of the. transaction, whether the latter involves a sale or the mere opening of the cash drawer to make change.
